Ninety-three samples of high land rice, “Bue Po Lo” variety from Mae Hong Son province and one sample of “Eto” variety from Chiang Rai province were evaluated for genetic diversity at Maejo University during June to December of 2012. Treatments were arranged in a Randomized Complete Block design with 2 replications. Cluster analysis of quality characters using NTSYS software was performed to construct dendrogram. The results found that sheath color, internode color, awn character, stem pattern, flag leaf pattern, panicle base pattern, stem vigor, secondary branch pattern, panicle pattern, panicle exertion and threshing were significantly different. While, leaf pubescence, ligule pattern and stigma color were not significantly different. Cluster analyses of...

Evaluations in genetic relationship amomg local rice genetic resources in the lower northern region were perform edusing cluster analysis method. In this study, a total number of 81 rice varieties were selected and clustered in both morphology traits by using the UPGMA of simple matching and agronomic traits by using the Square Euclidean by Ward method. From the morphology traits grouping results, there were 14 clusters (G1-G14) with4 main clusters i.e.Group 12 Group13 Group 2 and Group 6 which could be grouped.The results also showed that Group 12 has the highest number of members of rice varieties that was 56 varieties. The characteristics of Group 12’s members were green leaf, green leaf sheet, white pollen, yellow grain, non-glutinous rice and the...

Thai sugarcane clones are continuously developed to obtain new varieties from old outstanding clones. Most of good parents still gave good progenies. However, a few varieties are widely popular. According to this reason, the features of the 95 clones from recommended varieties, elite clones and land race clones were studied to find out good guidelines to utilize them to improve yield and high sugar content of new sugarcane clones. Each sugarcane clone was planted in 1 row per 5 meter long, and distance between row was 1.4 meters (harvest 3 meters) during April 2011 to April 2012 at Thaphra site, Khon Kaen Field Crops Research Center. Agronomical and botanical traits were recorded in every stage until the harvest. The results showed that more than 50% of...

Objective of this study was to study the genetic diversity in Giant Freshwater Prawn in Thailand from 4 locations, which were Khon Kaen (KK), Samutsongkhram (SK), Suratthani (SR) and Angthong (AT), with a total of 100 samples. Microsatellite technique with 13 primers and separating on 6% denaturing polyacrylamide gel were used in this study. The result showed that polymorphic loci had 105 alleles, the average number of alleles per locus was 8.08. The frequency of alleles ranged from 0.00 to 0.88. The average expected heterozygosity at all loci was 0.73 and the genetic distance ranged from 0.15 to 0.20, showed that the population from Samutsongkhram and Angthong were genetic the closest, while the population from Samutsongkhram and Suratthani were the most...

Disease is a major problem in the swine production. The study of genes associated with disease resistance characteristics is used to select for innate immunity in swine. The Mx1 gene was found to have potent antiviral affect against some virus and can be hereditary. The study of Mx1 polymorphisms in among 3 pig breeds (Thai native pig breeds, Chinese pig breeds and European pig breeds) were found SNPs in exon 8 (c. 1022C>G; 1078A>C) that has allele frequencies of statistical significance between the breeds. (P<0.05) The two variant in exon 15 found silent point mutation (c. 2120G>T) และ 11-bp indels (c.2117_2128 indels CGGCGCCGGCT) that has allele frequencies of statistical significance in some breed (P<0.05)especially in German Landrace and...

The phylogenetic analysis of phytoplasmas focused on the nucleotide sequences of the intergenic 16s-23s rRNA spacer region that primers enable the amplification of a 210 bp fragment by nested-PCR, are established for studying of genetic diversity of phytoplasma associated with diseases of sugarcane and some grasses in Thailand. In this present study, 99 phytoplasma infected sugarcane samples exhibiting various phenotypic symptoms and 15 samples of grasses showing white leaves were collected from many locations in Thailand and subjected for nucleotide sequencing. Phylogenetics tree based on 16S-23S ITS gene sequences showed two primary clusters: (1) phytoplasmas that cause diseases in sugarcane and (2) phytoplasmas that cause diseases in grasses. The...

Amplified fragment length polymorphism (AFLP) and biotype-specific markers were used for identification of genetic diversity and biotypes of rice gall midge, Orseolia oryzae in Thailand. Pupae and adults of the gall midges were collected from 19 field locations of 12 provinces during 2006 - 2007. Total of 242 polymorphic AFLP bands were generated from 12 selective primer pairs. Cluster analysis, performed by the UPGMA, separated the gall midge populations into four distinct groups. To identify the biotype, five specific-biotype markers were used to characterize the collected gall midges. Two biotypes of the gall midges, biotype 2 and 5, were identified from all populations used in this research. The results showed that the genetic diversity was not...

Weedy rice (Oryza sativa f. spontanea) is one of most serious weeds in direct-seeded rice production. High genetic diversity and adaptability of weedy rice made it very difficult to control in the rice field. This study aim to assess genetic diversity and population structure of weedy rice populations from Lower North, Northeast and Central of Thailand in wet of 2009 using twelve microsatellite markers. Genetic diversity and population structure of weedy rice were determined and compared with seven common wild rice populations and seven check varieties commonly grown in these regions. Weedy rice populations in this present study were hybrid between common wild rice and crop rice. The population structure of them was structured into 2 clusters according to...

Chaba Thongpaiyai; Anucha Wongpraneekul; Prasert Chatwachirawong.
Objective of this study was conducted to determine the diversity and relationships among commercial sugarcane varieties in Thailand. The pedigree in each variety was traced back to the original ancestors. The coefficient of parentage was calculated from records of 70 varieties, and a dendrogram was drawn using the unweighted pair-group method using arithmetic averages (UPGMA) of clustering. Pedigree data showed that Thai commercial varieties were only bred from 26 exotic varieties. The analytical results indicated that many sugarcane varieties had higher close relationship with OCSB3 (37.3%) than UT1 (20.4%). S. officinarum was major genetic contributor (25.1%) whereas S. barberi, S. spontaneum, and S. sinense were 10.8, 5.9, and 2.4%, respectively. These...
